Abstract:
A novel method for refurbishing a rubber disc used in a recycle machine comprises the steps of cleaning and sanding the surface of the disc; priming at least the surface of the disc with a liquid primer or interfacing agent (adhesive); placing the disc in a portion of a mold; charging or filling the mold with a polymer (synthetic rubber or elastomer) mixed with a suitable catalyst, hardener or activator; allowing the synthetic rubber polymer to exothermally cure inside the mold; and withdrawing the disc from the mold. The resulting refurbished disc is characterized by a new outer surface layer (synthetic rubber) adhered to the original rubber disc. In an alternatively preferred method, one or more relatively small holes are formed in the surface of the disc prior to molding the new outer surface layer on the disc whereupon the strength of the bond between the new outer layer and the original disc is enhanced.
